it works well for now. there is a USB port behind so that you can charge our Xperia magnetic and trendy as other equipment. by against the wire we see on the image is not provided (it's really great damage) the second negative, the wire is provided for the trendy black (if I buy a white is that I want all white ..) and this last is L shaped what it is that difficult 2nd plug the wire
(Personal solution: buy a white and another for connecting other devices)
